On distributed database requirements for the intelligent network

Ways to manage the distributed database requirements for the intelligent networks (INs) of the future are considered. The nature of the program decision-making tables and data which will be allocated between the switching nodes and the IN database platforms is discussed. The implications of matching current centralized switching system translation lookups and program decision speeds with lookups performed at distant IN database platforms by means of intermediate data links with limited (56 kb/s) transfer speeds are examined. It is suggested that these aspects must be considered before standard distributed-database management techniques can ensure overall performance integrity
